Here's an interesting article about a new Hebrew translation of Maimonides' "Guide of the Perplexed," as well as a good summary of why Maimonides is a useful role model for rabbinic leadership today:

Regarding the book's relevance for today's generation, Kleinberg admits that "tackling the challenge of Greek philosophy is not a burning issue in the present era. Nonetheless, great importance should be attached to the presentation of a model that we are not so familiar with in our generation: another breed of rabbinical scholar, namely one who, in addition to being an expert on contemporary scientific and philosophical literature, seeks to cope with it and with the relationship between that literature and the Jewish religion."
In this context, Schwartz notes the long tradition of Jewish works that seek to bridge the gap between Judaism and contemporary thought: from the days of Rabbi Saadia Gaon's "The Book of Beliefs and Opinions" in the 10th century, through "The Guide of the Perplexed," to Nachman Krochmal's "Guide to the Perplexed of Our Age" in the 19th century and to Rabbi Joseph Dov Soloveitchik, who tried to bridge the gap between Judaism and 20th-century Western philosophy.
